Looking for feedback on carbon buildup on tips versus no carbon.
Would like to know how many of you have pretty much spotless exhaust tips on the inner rim after let's say 2-3 weeks of driving, vs black carbon buildup after 2 - 3 weeks of driving. I currently have almost no carbon buildup after two to three weeks of driving. What's weird, is I remember periods of time in the past where I would have carbon build-up after 4 days. Something has definitely changed. Car is running amazing. Hoping I am not too lean.
